LENS BARREL AND CAMERA EQUIPPED WITH SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17975726 titled 'LENS BARREL AND CAMERA EQUIPPED WITH SAME
Simplified Explanation
- The patent application describes a lens barrel design that includes various components such as a lens mount, a fifth lens group unit, a cam frame, a cam pin, a cam pin holder, a main shaft, and an urging spring. - The cam frame encloses the fifth lens group unit and has a cam groove. - The cam pin is engaged with the cam groove and can move in the optical axis direction. - The cam pin holder is attached to the fifth lens group unit and holds the cam pin, allowing for relative motion in the optical axis direction. - The main shaft enables movement of the fifth lens group unit in the optical axis direction. - An urging spring is provided to the fifth lens group unit and applies pressure to the cam pin holder, pushing it towards the subject side in the optical axis direction. - When a teleconverter is mounted to the lens mount, the urging spring contracts, causing the fifth lens group unit to retract in the optical axis direction.
Original Abstract Submitted
A lens barrel () comprises a lens mount (), a fifth lens group unit (), a cam frame (), a cam pin (), a cam pin holder (), a main shaft (), and an urging spring (). The cam frame encloses the fifth lens group unit , and has a cam groove . The cam pin moves in the optical axis direction in a state of being engaged with the cam groove . The cam pin holder is provided to the fifth lens group unit in a state of being capable of relative motion in the optical axis direction, and holds the cam pin . The main shaft allows the fifth lens group unit to move in the optical axis direction. The urging spring is provided to the fifth lens group unit , urges the cam pin holder toward the subject side in the optical axis direction, and contracts when the teleconverter is mounted to the lens mount to retract the fifth lens group unit in the optical axis direction.
